Should be an option to break stacks up or sell excusively as a full stack.

Recently Decided it was time to clear my retainers of all the junk they'd had and found that discovered that nothing was selling, yet the price history's had people buying often at much higher prices,

If I recall correctly 1.2 had a stack only check box where if I listed 99 of an item the buyer had to buy all 99 if that box was ticked, if it wasn't ticked a buyer could buy 1, 10 or any number they wanted..

so if I listed a stack of leather for example players could buy 1 or 2 or even the whole stack, then on other items like arrows you could set it so players had to buy the whole stack and not just buy 2 arrows from a stack of 999 or something.

I really think ARR should work the same way, this way players that want to offer reduced prices for full bulk only sales can do so, and players who wan't to sell on an individual price don't need to spend 20 minutes listing 20 items on a 1 by 1 basis.
